A mild approach to the synthesis of 4-amino-8-(arylamino)pyrimido[5,4-d] pyrimidine 3-oxides

The reaction of benzylhydroxylamine with 6-cyanopurines leads to the formation of 7-benzyloxy-8-imino-7, 8-di-hydropyrimido[5,4-d]pyrimidines. The hydrochloride of these compounds, isolated upon addition of aqueous hydro-chloric acid, is a convenient prec
